Looking for spring bolt measurements

[norville]

Hey folks, If my 77 burb doesn't sell. I'll be looking to lift it asap to get my tires under it. So Does anybody know the correct length and thickness of the front spring bolts? Also how about the u-bolts for D44 3/4 ton. I'm hoping to cut down on the parts running. I'm doing a shackle flip for the rear.

Thanks,

anybody running bfg 35x12.50's 16.5 on stock 6.75" rims?? No good?

9/16 on the diameter & i believe mine are 6" long. U-bolt length will depend on the thickness of your spring pack but are easy to shorten w/ an angle grinder and a cut-off wheel.

Every spring bolt i've ever seen on a GM truck was 3/8" diameter and the length will need to be determined by the thickness of your spring pack but most spring bolts are 12" long and you cut them to length. The head of the spring bolts does vary though but most are 9/16" heads with a 3/8" thread.

thanks guy's

The springs arent any thicker than my factory pack, I'm hoping to pick up the ubolts at pep-boys before I start. The bolts I guess I grade 8's from the hardware store. I've never had good luck trying to save the bolts , it's much faster to just cut them off with wheel.

thanks

I'm thinking bolts for the front bushings/spring eye. I'll leave this stuff to people that can read.

Johnny, you were correct I was looking for both.
